説明

An epidemiological evaluation of the effect of dental health education on school children was made. The subjects were from two elementary schools located in a similar geographical and socioeconomic environment in the suburbs of Gifu city. One served as the test school and the other as the control school. The test school had approximately 1000 school children fromthe first to the sixth grades, and the control school had about 900 children. Dental health care education was given to the children in the test school through the teachers who had been well instructed in dental health education by staff members of Department of Pedodontics Asahi University School of Dentistry. Later the oral hygiene level of the children was evaluated by the visible plaque index (VPI) and the gingival bleeding index (GBI) by Ainamo & Bay.<BR>The results were as follows. The mean VPI and GBI in the test school showed a significant decline. The tendency of this decline follows the negative acceleration curve which is characteristic of the learning process curves. In addition, the mean VPI and GBI values in the test school were significantly lower when compared with the control school and either the VPI or GBI values were higher in boys both in the test and the control school. Also the number of children with a score of 0 for the VPI and GBI values increased significantly in the test school.<BR>From the results obtained in the present study; it was suggested that dental health program given by the teacher could be an effective approach for improving the dental health conditions of school children as far as the VPI and GBI is concerned.
